xsuki Posted March 27, 2012 Report Share Posted March 27, 2012 I think we have 6, i've done two - Photosynthesis (IA1) Body measurements (IA2), what are the rest? Reply Link to post Share on other sites More sharing options...
Sandwich Posted March 27, 2012 Report Share Posted March 27, 2012 There aren't set IAs, these are ones your school has made up for you. You can technically do IAs on anything you want. So ask your teacher, because it's a system created by them if they've told you they all have numbers etc.! At least a few of them they won't be able to give you a topic for because you're marked on designing them yourself. Reply Link to post Share on other sites More sharing options...
Eastcoast93 Posted April 20, 2012 Report Share Posted April 20, 2012 It is up to the schools. A general direction will be given, however it is really up to you what you investigate.I did IAs on these topics:Effect of stream velocity on abundance of mayfly nymphsSubstrate concentration and enzymesRespiration rate of peasPea germination Reply Link to post Share on other sites More sharing options...
Jaydon Posted April 26, 2012 Report Share Posted April 26, 2012 You can pretty much do any IA that the school says you can, but those topics will have to be relevant to the IB. For example, your school could tell you to investigate factors affecting the capacity of the cardiorespiratory system, and you could choose to investigate VO2 max, heart rate, or lung capacity. It's really up to you, unless of course your school tells you to.My school tends to do one IA for each topic (therefore per term), with Anatomy and Physiology being split into two separate IAs.Here are the IA topics that I have currently had and the relevant topics:Topic 1 Cell Biology - OsmosisTopic 2 Biochemistry - Enzyme digestion rateTopic 3 Genetics - Fruit fly simulation (wasn't actually an IB IA as such)Topic 4 Ecology - Water qualityOption E Neurobiology and Behaviour - Reaction time/rateTopic 5 Anatomy and Physiology - Microbiology (we're not submitting this to the IB just in case)Option H Further Anatomy and Physiology - Capacity of the cardiorespiratory system Reply Link to post Share on other sites More sharing options...
